Disk drive mechanism

Abstract

A disk drive mechanism includes a spindle mounted on a motor-driven shaft and including an annular wall having a support surface, a flexible hub mounted on the motor-driven shaft and composed of a plurality of segments including a radially outward flange, the support surface and the segments coacting to center a floppy disk with respect to the motor-driven shaft, the support surface and the radially outward flange coacting to clamp the floppy disk therebetween, a collet mounted on the motor-driven shaft in fitting relation to the flexible hub and having a radially outward flange having a circumferential surface, and a resilient O-ring interposed between a surface of the flange of the flexible hub and the circumferential surface of the collet.

What is claimed is: 
     
       1. A disk drive mechanism comprising: (a) a motor-driven shaft;   (b) a spindle mounted on said motor-driven shaft and including an annular wall having a support surface;   (c) a flexible hub mounted on said motor-driven shaft and composed of a plurality of segments including a radially outward flange, said support surface and said segments coacting to center a floppy disk with respect to said motor-driven shaft, said support surface and said radially outward flange coacting to clamp the floppy disk therebetween;   (d) a collet mounted on said motor-driven shaft in fitting relation to said flexible hub through a resilient O-ring and having a radially outward flange having a circumferential surface; and   (e) the resilient O-ring interposed between a surface of said flange of said flexible hub and said circumferential surface of said collet.   
     
     
       2. A disk drive mechanism according to claim 1, wherein said segments have a fitting portion fittingly engageable with a radially inward surface of said annular wall.
